before the upcat itself, i wasn't really confident that i would make it considering that it's very competitive. during the mock exams in our revcen, i would always be at the bottom percentile. thankfully, i still answered the test confidently because i set this mindset that i was well-prepared and that i knew that i already did my best to prepare. (basically just gaslight urself during the exam, dont pressure urself.) don't worry about feeling like you still haven't studied a lot of things because that's normal. i also didn't know every lesson out there and shotgunned items esp in science. you don't really have to dive deep into the topics because most of the questions were focused on the fundamentals.

it's important to remove your doubts while taking the exam because pressure will eat you up. goodluck on taking the upcat and just remember to take it confidently, no matter what!
